Application filed February 20, 1914. Serial No. 819,989.

, of which .the following is a specification.

This invention relates to certain new and 4 useful improvements in valveextractors for wells.

The primary object of the invention is to` Iprovide inconnection withthe valves in A`deep water or oil wells, an advantageous lwmeans adaptedto pound. and vibrate the valves'to clear the same from obstructionswhich prevent a proper seating thereof. It k 'is also designed tofurnish a structure which i at the same time will be serviceable forenffaeino' the dee valves for ullino the saine C b P3 D out of thewells, and Such a structure is now contemplated which will facilitatethe accomplishment of these objects with a minimum expenditure of timeand labor as well as loss oi' oil or water. In the accomplishment ofthese objects moreover, the same is rendered more advantageous by thevemploy- `nient of the presently devised coil spring attachrnent forminga spring lock nut adapted for preventing a mutilation of the threadsupon the end of the bolt when the latter is descending into the welltubing upon vthe end of the sucker rod for the purpose of'engaging thevalve cage. rIhis object also inchicles a maintaining of the nutentirely covering the bolt threads when the same is initially placed incontact with the top of the valve cage, either for pounding the cage orfor engagement with the top threads of the valve in the pullingoperation.

A still further object is the provision of such a coil spring forholding the nut from revolving upon the bolt during the poundingoperation but permitting the bolt to revolve for engaging the threads ofthe valve cage. v

lith these general objects in View and, others that will appear as thenature of the invention is better understood, the same consists in thenovel construction, combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings, and pointedout in the appended claims.

In the drawings forming a part of this application and in which likereference cha-racters refer to corresponding parts throughout theseveral views z-Figure 1 is a side elevation of a valve cage having thewithdrawing mechanism secured thereto, such structure illust-rating theinvention combined therewith. Fig. 2 is a central longitudinal sectionalview thereof. Fig. 23 is a transverse sectional view taken upon line 3-3of Fig. l, and, Fig. i isv a top plan vview ot the grasping nut ofv thedevice.

Referrincr more in detail to thd drawinfrs a valve cage 10 denotes thebottom or standing valve ot' the usualconstruction and having a flat top11.

. A socket 12 is :provided with internal screw threads 13 tor securingthe same to the endof the sucker rod when desired tov lower the socketinto the well. A threaded extension 11i upon the lower end of saidsocket receivesthe threaded nuit 15 having side jaws 1G adapted to graspthe cage of the standing valve.

A coil spring 17 Lnoircles the upper unthreaded portion 1S of the socketextension while the lower end 19 of said spring is downwardly turned forpermanently en gaging within an opening 2O in the top face of the nut15. The lower-ace Q1 of the socket is provided with a circular recess 22terminating in an abutment 23 and against which the upper free squaredend of the spring is adapted to abut. .As normally positioned, the screwthreads 14 are entirely concealed by the nut 15 and are so held by saidspring which is secured to the nut by reason of its upper end being inengagement with said abutment. Vviith this construction it is thereforeevident that with the screw threads concealed within the nut 15, thesocket and nut may be readily l0- cated in the well and the nut broughtforcibly down upon the Hat top 11 of the standing valve without thepossibility of-injuring the threads either upon the socket eX- tensionor upon the threaded bore 24 at the top of the valve.

The jaws of the nut 15 are here shown as adapted to seat between theside pieces of the valve cage and thus positiornthe socket shank inalinement with the threaded bore of the valve and to be engaged therebyalthough it is evident that the present arrangement of lock nut may beemployed in other forms for engaging different kinds of cage valve tops.

lVith the elements in the position shown in Figs. 1 and 2 of thedrawings, it will be seen that the threaded extension of the socket maybe screwed through the nut l5 and intor the valve bore 24: during whichoperation, the top of the spring 17 -is ratcheting over the abutment 23upon each revolution of the extension, While at the same time the coilspring is being compressed. Both upon the final compression of thespring and during the engaging operation, any reverse movement impartedto the socket and its extension results in contacting the abutment 23forcibly against the upper free end of the spring, and therebypreventing any further unscrewing of the connected elements. It isobvious that either end of the spring may be removed from its engagementwhen the device is extricated from the Well and thus permit of adis-assembling of the parts and the disengagement of the valve cage fromthe socket ex- :tension and nut and by which it has been raised from theWell.

While the forms of the invention herein shown and described are Wlratare believed to be preferable embodiments thereof, it is nevertheless tobe understood that various changes and modifications may be had Withoutdeparting from the spirits and scope thereof. y

extension, and an angular groove partiaily surrounding said extension7 anut upon said extension, a helical spring surrounding said extension andsecured to the upper face of said nut, the upper end of said springseated Within said circular groove and the end of f said spring adaptedto engage the end of said groove.

2. A device of the class described comprising a socket member having apartially threaded extension, a nut upon said extension, said socketmember having a curved socket in the bottom thereof terminating in anabutment, a spring having one end secured to said nut and -its other endnormally mounted with said curved socket with the end threads of theextension covered by said nut, the upper end of said spring adapt ed forratcheting over said abutment durmg a turning of `the socket inonedirection and for resiliently preventing rotation in the op positedirection.

In testimony whereof we affix our signatures in presence of twowitnesses.
